Intel is expected to unveil its 4th generation Core "Haswell" processor family by early-June, along the sidelines of the 2013 Computex event. In addition to being available in 1000-unit tray quantities to OEMs, the desktop variants of these processors will be available in their familiar retail box packages. Multiple sources confirm that pricing of these chips will be largely identical to that of the current Core "Ivy Bridge" series, with succeeding next-generation part for each current generation one. The table below describes their US MSRP (excl. taxes).

I guess I'll stick with my 970 and 2600k for my main rigs... But if I decide to upgrade or side grade.. I'll change out my 2600k and give it to my daughter which is still running a Q9550.. She won't notice a difference, but I'll see it in crunching.

Don't know about the Q6600@3.6, but for my i5 750@4.0 the Nvidia 670@1350 is the bottleneck in 90% of the games. Sure you might get better average FPS with faster CPU, but I'm looking at FPS dropping below 60.

I do want to upgrade (look it's shiny!), but I can't find a logical reason.

For gaming, i5 vs i7. Until now almost no game took advantage of the extra L3 or HT, the situation is slowly changing. It would be awesome to see the difference in modern games when both CPU are at the same clock.
